A report on the 5th Internet, Law and Politics Conference hosted by the UOC in July 2009. The author, who attended the conference as a rapporteur and wrote a live blog' during the two-day event, reviews some of the contributions, reflects on the theme of social networking sites (pro or con'?) and explores the different approaches of the disciplines of law and political science, suggesting that the increased importance of such sites means that considerations such as privacy, security, political engagement and copyright are the subject of necessary and interdisciplinary public debate.
